  • Extraction process using supercritical carbon dioxide
    Patent number: 10286336
    Abstract: The present invention provides a method of using CO2 in an extraction process without the use of mechanical pumps to control CO2 density. In particular, the invention relates to a process for extraction of one or more components from a plant material by manipulation of density of CO2 in the extraction vessel via creating a temperature differential between the liquid CO2 supply and the extraction vessel.
    Type: Grant

  • Virtual reality network with selective distribution and updating of data to reduce bandwidth requirements
    Patent number: 5950202
    Abstract: A virtual reality system has a database for defining one or more three-dimensional virtual spaces. A communication unit establishes a communication between the database and a user, and a data communication unit communicates data from the database to the user so that the user's computer may display a portion of a selected virtual space on the user's head mounted display. The communications unit also receives data corresponding to the position, orientation, and/or movement of the user relative to a reference point and uses the data to define a virtual being within the virtual space, wherein the position, orientation, and/or movements of the virtual being are correlated to the received data. Preferably, the data communicated to the user typically corresponds to the portion of the virtual space viewed from the perspective of the virtual being.
